Printing apparatus

Abstract

According to one embodiment, a printing apparatus includes a transverse adjusting mechanism and an abutting frame. The transverse adjusting mechanism moves a passbook in a direction perpendicular to the conveying direction to make a first side of the passbook abut on the abutting frame while the passbook set to be inserted to a medium inlet is being received and conveyed. Accordingly, the transverse adjusting mechanism positions the passbook with respect to a printing region of a dot head, and retracts the abutting frame from a conveying path while a statement paper is being conveyed. The printing apparatus includes a controller to determine whether the first side of the passbook is placed inward from the abutting frame. The controller controls receiving and conveying the inserted passbook based on the determination result.
